Was going to mention the little B2, but I just knew you'd slip it in there, all oily, like!
Going to collect Mercury S later (as long as it's okay). If he didn't have anything, all this talk of yours of the B2 was making me more than a little interested in one as a short range ratter....Those dimensions are way more than adequate, no? You could even lose loads of swept volume and have a really handy, sweet little, reduced stroke 9 foot pounder for Roland and his mates!
